Why can't this kind of stuff happen in real life?

i dunno i want stuff like that to happen too

probably because no one is Merida - Legende der Highlands enough to sing like that in front of alot of people

ok would Du like to make a scene in public if Du would then do so

I have no idea but it would be very amusing if that happened. Then life would be a musical. But then high school would be High School Musical.
